The valve adapter is developed for installations in ceilings and walls. It is manufactured in a way that it can cross most common heights and thicknesses such as walls, screed floors or the space behind suspended ceilings.
The adapter can be cut to length with normal tools for further assembling with the end-piece of the ventilation system; the supply valve or extract valve.
The adapter has two Air Excellent ductwork connections. The valve adapter is delivered with a dust-cap at the 125mm end. From the two Air Excellent ductwork connections, one is delivered with a detachable closing cap.
